OK, maybe it just munched vegetation, small animals and eggs. But this newly named dino looked like a cross between a chicken and a bulked-up ostrich. Five-inch claws? We'd have stayed out of its way.
Einstein's theory of relativity explains the universe. But — in part because of a math error — some recently uncovered work by the great physicist is wrong. Really, really wrong.
Acting fast can be key to preventing permanent damage from a stroke. But many women don't realize that face or arm numbness, speech trouble, or abrupt, severe headache can mean it's time to call 911.
The approach would recognize changes in behavior and in the brain. Right now there aren't treatments that slow down the disease, but identifying high-risk patients early on could help with prevention.
Estimates from the Alzheimer's Association show that more than 5 million Americans are living with Alzheimer's disease. Those numbers don't include the millions whose brains show signs of the disease but whose symptoms aren't obvious yet.
Despite evidence to the contrary, many Americans believe cellphones cause cancer and that health officials are covering it up. Discredited theories about vaccines and fluoridation also remain popular.
An analysis of DNA from ancient and modern chicken bones from the Pacific islands shows they are genetically distinct from South American birds.
Two mapmakers made the place up. It wasn't real. Then, oddly, it popped into being. I am not making this up. It happened. Then it un-happened.
Giant lizards are coming out of hibernation in Florida. Trouble is, Robin Sussingham of WUSF reports, they're members of an invasive species with a taste for the eggs and hatchlings of native animals.
Drs. Deirdre Barrett and Robert Stickgold discuss the case of Dion McGregor, a sleep talker whose vivid and expansive somniloquies are the subject of the album, Dreaming Like Mad with Dion McGregor.
Dark chocolate may help the heart and waistline. Now scientists have figured out one reason why: Bacteria in the gut turn cocoa into compounds that lower inflammation and make us feel full.
Andrei Linde, one of the founding fathers of cosmological inflation, answers the door to the news that his theory appears to have been confirmed.
Physicists say they've discovered a faint signal from just moments after the universe began. If confirmed, it could revolutionize our understanding of the cosmos. But not everyone is convinced.
In the 1980s, NASA engineer Robert Farquhar came up with a sly plan to divert the ISEE-3 satellite from its original path to visit a comet instead. Now Farquhar has another big plan for his "baby."
At issue in Iran nuclear talks is a heavy water reactor the country is building. Iran says it wants the reactor for medical research, but the West is worried that such reactors can produce plutonium.
Paris is suffering from the worst smog it's seen in decades. Associated Press Paris Bureau Chief Angela Charltan explains the ways the city's dealing with the smog, including restrictions on drivers.
Physicists using data from an Antarctica telescope say they've observed evidence of primordial gravity waves — in other words, echoes of the Big Bang. If real, this may be a big advance for physics.
Chemicals in cigarette smoke can settle on clothes, furniture and walls. Researchers call this thirdhand smoke and say laboratory experiments suggest it could be hazardous.
Programs — some already on your smartphone — are preparing useful information based on your past behavior, ushering in the era of predictive, or anticipatory, computing.
Roughly one in five unvaccinated people had the flu between 2006 and 2011, but only a quarter of them had symptoms, a study found. That could affect how the virus spreads.
